Hello, I teach some one-time workshops. While everyone is required to Bring/Own a laptop workshop attendees only have a Chromebook. Instead of turning those people away, I want to be as inclusive to whatever hardware people have as possible.

I've done some googling/searching and it seems as though the web editor requires a plug-in, but that requires a subscription fee? Even at $1 a month, I can not have people signup and start entering a credit-card number in a class (it just comes off as awkward or I'm trying to sell them something in addition to the workshop).

I want as little friction as possible with as many happy people getting started quickly.

Is there a free way to use a chromebook to program an arduino? (These would mostly be Uno R3).
